Coinbase seems to be going to great lengths to try and distance themselves from the so-called "rogue overseas support agents".

If they were Coinbase employees or contractors, that means the company basically sold its own data to hackers, who then turned around and demanded a ransom.

Reimbursing duped customers makes sense, as it seems like they would have a pretty straightforward case to make in court that Coinbase's actions led to their loss.

I'm more curious if someone who feels the need to move, change banks, change their email, hire a security detail etc. could successfully sue the company to recover some or all of those costs.

I have been receiving regular spear phishing calls from these guys, or someone who bought the leaked data, with classic tactics like claiming that I need to confirm a potentially fraudulent transaction. They speak perfect English with an American accent, sound very friendly, and have knowledge of your account balance. Thankfully on the first call I realized it was a scam right away, and Google's call screening feature takes good care of the rest. Wish I could forward them to Kitboga[1].

I guess they didn't have as much luck as they wanted scamming Coinbase's customers, and once they had their fun they decided to try extorting Coinbase themselves.

If you had any significant assets on Coinbase at any time prior to this breach, spear phishing is the least of your worries.

Coinbase not only leaked your full name and address, they also gave up your balances, your transaction history, and images of your government identification.

People with "significant" crypto balances are being assaulted on the street and in their own homes, and family members are being kidnapped for ransom.

"Significant" in this case can be $10k or less.

Until now, your best defense secrecy. Never talk about crypto in public in any way that could be traced to your real-world identity.

Thanks to Coinbase that defense is now gone.

The bad guys can see who has ever had a significant balance on Coinbase (even if they don't right now), whether that balance was sold for cash and how much, or if you've ever transferred tokens off the exchange to a self-custody wallet.

Now the bad guys know who's worth kidnapping for ransom and where you live. For most people, a Google search of your name and home address turns up the names of family members who would would also be lucrative targets for kidnapping and threats of violence.

Coinbase will never be forced to reimburse all the damage they've done because the true cost would bankrupt the company.

I wonder why, select a person completely at random and by median you'll get just as much from what they have sitting in their checking account. Select a nicer area for an order of magnitude more. That's not encouragement to go assault people in their homes or kidnap families... just confusion.

Yeah, but banks and the normie monetary system has a lot more safeguards in it when it comes to account transfers. Or at least, they appear to have them.

suzzer99 · 1h ago
The median person does not have $10k sitting in a checking account that they can easily withdraw. My gut feeling is that the threat of kidnapping is a lot more serious in some countries. The US maybe not so much.
zamadatix · 55m ago
Good point, perhaps the lower $ examples are about other countries where that may be a lot more than median transactional account holdings and maybe that concern is part of why folks were using crypto holdings.

thepasswordis · 4h ago
The problem is that it seems like the data that leaked is also the data that would be used to do account recovery.

And what that means is that

1) If you lose access to your account (through either your own fault, or coinbases fault) that the process of recovering it may not be so straightforward anymore.

2) Hackers can try to “recover” accounts now using this leaked info.

This is a huge problem. What coinbase needs are IRL offices where you can go and do things like account recovery, and where people trying to steal money can be caught and prosecuted (and makes a huge barrier for the overseas thieves who are usually doing this)

The only solution here is: hardware 2 factor like yubikeys.

Coinbase is identical to a bank because it holds customer funds. Your comment isn't quite the dunk you think it is. Blockchains allow money to be held anonymously without any banks involved. Centralized exchanges are just profiting on speculation and probably should be banned.

Yes, I think I’m familiar with the crypto enthusiasts defenses that all boil down to looking at a single aspect of their system in a vacuum and not realizing that if anyone wants to functionally use crypto as a currency and not as a speculative asset or tool in crime, then all these aspects actually have to work and work together

I don't really care about crypto personally (volatile shitcoins) but I think that's a straw man argument. They all know it gets troublesome when it comes to dealing with fiat transactions. The hardcore crypto enthusiasts want to avoid fiat entirely.

If only hardcore crypto enthusiasts who didn't want any fiat had cryptocurrency bitcoin would be worth a couple dollars a piece and 99% of other cryptocurrencies wouldn't exist. The vast vast majority of people who have crypto are doing it because they think they can get rich from it and that's why anytime it's talked about it's talked about in terms of fiat values

codedokode · 1h ago
As I understand, the root of the problem is that Coinbase kept lot of sensitive information, including photos of IDs. If Coinbase was fully anonymous, and didn't require any KYC, the impact of the leak would be insignificant because it would be difficult to link user number 12345 with some real-world person.

So if we want to constrain impact of such attacks, we must make companies keep less data and delete them faster. For example, instead of storing a photo of ID, store just a checkbox that the person showed their ID and it was valid.

This applies not only to cryptocurrency, but to any company like Google, Uber, Amazon etc - if they didn't keep extra data, there would be little value in the leaks.

So the blame is not at cryptocurrency, but on companies not wishing to delete the data and governments demanding them to collect the data not necessary for operation. It's the government and capitalists who create problems out of nowhere.

Looking at their blog post, it seems like they paid customer support agents to hand over sensitive data. The attackers did not have access to any agent accounts themselves, and the customer service agents were accessing data they were already privileged to anyways.

https://www.coinbase.com/blog/protecting-our-customers-stand...

lxgr · 30m ago
Logging and retroactive auditing seems like the very least they should do. Even asking the customer service agent to first provide identifying details of the customer they can't easily know or guess by themselves doesn't seem excessive, given the sensitivity of the information.

It won't work for 100% of all calls (what if the customer is locked out themselves etc.), but those calls can then be handled by even more closely monitored agents.

"Less than 1% of monthly transacting customers" means up to 1% were accessed – that seems very high, i.e. much higher than the number of customer service contacts I'd expect.

gkoberger · 2h ago

scotty79 · 2h ago
no-reply is a good practice. No business should ever encourage their customers to reply to the emails they are sending out. That's what scammers do.

To contact the company you should go to company website at the address you know (which shouldn't be given in email as well), log in and send a message through internal message system, possibly referring to the email that you recieved through a random code (those can be auto-suggested if they recently tried to contact you by email).

If you do anything else your communication knwowingly mimics communication of a scammer.

Unrequested email should always only be one way communication. Email is too untrustworthy for it to be anything more.

> No passwords, private keys, or funds were exposed and Coinbase Prime accounts are untouched.

I'm curious why no Coinbase Prime accounts were part of the leak (assuming that's what they mean). Is there some sort of additional layer of data protection behind the Coinbase Prime paywall? Or perhaps those accounts were intentionally avoided as they would presumably belong to more savvy users.

czk · 2h ago
Coinbase Prime is its own exchange with its own support (actual humans in the USA that are available to chat to). It's for "institutional investors" so unavailable to most customers without the proper credentials/paperwork. They don't share the same outsourced "support" as the regular exchange, which appears to be the attack vector here.

molticrystal · 3h ago
And the reason Coinbase has to keep all that sensitive stuff, much more than what would be required to identify and authenticate you, which you hope will never be stolen, is because of know your customer laws, so you can thank your government that pictures of your passport got stolen and for whatever criminals and rogue Coinbase employees do with that info.
ryuhhnn · 3h ago
There are very good reasons for KYC, the problem here is not the government regulation, it's once again private companies being sloppy with their customer's data because sloppy is cheap and it's not their info on the line, it's yours, so there's little motivation for them to safeguard it _unless_ they're compelled to do it by law.

The people who designed a government regulation to deputize private companies couldn't possibly have known how sloppy private companies are with other people's data?

There should be an ISO standard with respect to how much power and information that front line customer support agents have. The more information you need, like changing passwords or accessing personal information, should get forwarded to higher level customer support agents with better training and more monitoring. This way you can design customer support experience with as little exposure to security issues as possible.
wepple · 2h ago
> better training and more monitoring.

That’s very load-bearing. It won’t help.

The CS reps are based in a LCOL country so the opportunity for theft is simply incredibly lucrative.

What is really needed, is customer-in-the-loop for access to their data. The problem is, not all accesses would make sense. Doing analytics over the data of the top 1% of customers, for example, requires some level of access, but would freak out those customers if they had to approve it.

Maybe it’s a naive question, but in many breach reports I see things like 'No passwords, private keys, or funds were exposed.' How come companies can usually protect that kind of data, but not emails, names, and other personal info?
selectout · 3h ago
Companies want the ability to use things like emails, names, and other data for user experiences (go to settings, see name and change it), advertising (target this address book for X ad), etc. So these are typically plaintext (oversimplified) and accessible by different systems while passwords or private keys have one use case only and can have a higher bar of protection.
LorenPechtel · 2h ago
Such data is typically encrypted and purely write-only, only read by the system itself. Thus it is only exposed if the database itself is exposed. If the leak was compromise of the systems that access the data (which appears to be the case here--insiders copied data they could access) the write-only info is not exposed.

I'm surprised they only demanded $20M. Surely that customer data is potentially worth, like, potentially orders-of-magnitude more.

Correspondingly I'd assume either a) paying the ransom doesn't take it off the market or b) the info they stole isn't that interesting.

    What they got

    - Name, address, phone, and email

    - Masked Social Security (last 4 digits only)

    - Masked bank‑account numbers and some bank account identifiers 

    - Government‑ID images (e.g., driver’s license, passport)

    - Account data (balance snapshots and transaction history)

You know how your bank asks you to verify details when you call?

Without the right details the customer support people don’t get entry into the customers account details.

Banks have been doing this for 30+ years..

Which is such a lame and flawed mechanism to avoid letting them access anyone's data. I mean what are you even trying to prove here? That banks care about customer's security when they can't even implement a secure 2FA which is not just an unencrypted text message

CS can validate without knowing the details, the same way you don't enter a password and then check to see if that matches the password in the system.

The fact that they keep blaming overseas customer support is pure blame shifting - you still hired someone and gave them access to all this data, Coinbase!

We don’t know if they had access to everything. They got data for “less than 1% of monthly transacting customers”.

No. Coinbase deals with fiat money, therefore subject to AML and KYC regulations.

The question was about customer support. AML and KYC regulations do not require that customer support persons know your PII. That can be kept firewalled from them.

Isn't the whole point of crypto to keep PII out of it completely? If not, what is all this non-sense for exactly, other than the typical goals of pyramid schemes?
ty6853 · 4h ago
The main point of crypto IMO is to have a large-denomination bearer asset.

This is overlooked most places but if you examine around the time the FATF finally pretty much eliminated bearer bonds, bearer stocks, and large bank notes was exactly the time crypto really took off.

You can do a background check, but the reality of the matter is that you pay citizens a living wage to do the work instead of offshore it into a country that pays pennies.

Bank tellers can take thousands out of the vault at any time and yet it seems it’s not a very big issue.

Maxatar · 3h ago
Bank tellers do steal money from the banks they work for though and banks invest a significant amount of resources and have a lot of policies to prevent it.

For example at many banks the teller might need to get manager approval for some cash withdrawals, even for seemingly smaller amounts of money. Despite what it may seem, it's not because of some distrust towards the client but a safeguard against internal fraud.

kragen · 4h ago
Bank tellers are constantly surveilled by cameras, security guards, and several-times-daily cash counting, and it's still easy to find accounts of them having stolen significant amounts of money before getting caught. These are all from within the last year:

Vannia Chatt: https://6abc.com/post/former-citizens-bank-teller-accused-st...

Mountee Brown: https://www.justice.gov/usao-md/pr/maryland-bank-teller-plea...

Being US citizens doesn't make people incorruptible. In fact, many other countries are less corrupt than the US. Someone in this very thread reports having witnessed bank tellers getting bribed in one of those countries: https://news.ycombinator.com/item?id=43996765

I've been through a background check designed to screen out people who were vulnerable to bribery. They interviewed my friends and family from the previous several years to find out if I was secretly gay, cheated on my wife, gambled, drank too much, used illegal drugs, or had money problems for some other reason. It took about a year. I think it would be hard for a financial institution to be economically competitive doing that kind of thing with their call-center workers, because their customers can't tell if they're secure or not, just how much their services cost.

bombcar · 4h ago
Then shift liability and let the insurers take care of it.

With a lot of this online stuff, no matter who gets your password or access to your account it’s you who has to take care of it. Whereas if the bank teller steals from the till it’s not your problem.

correct, but what's the alternative? they're paid peanuts because it's not exactly the kind of job you ever pay out the wazoo for. the only thing that comes to mind if I'm Brian Armstrong is going all in on AI bots that can get to 90% of the way there (maybe 95%) and then have domestic based humans that are paid more with (presumably) a less probability of being bribed. but realistically, the only way to stop something like this is going 100% AI bots but then that comes at the expense of customer satisfaction, and also bots that are exploitable through prompt manipulation.

alternatively limit the roles and what the offshore people are able to do, but then any escalation means domestic people, which brings us back to "well at that point just use AI to automate easy tasks"

egeozcan · 3h ago
Normally payment should follow the amount of power/responsibility. If you pay someone peanuts but they have root access to prod, then you should pay more or restrict their credentials. Same applies to being able to access PII.

Small set of privileged employees who work from the home office and are compensated to match. If an issue requires their attention, it takes time to resolve. But it's resolved securely. In essence, what Google does.

Bribes are one thing, but threats could also happen. This is a big part of the reason why I absolutely hate entities that think residential addresses should be public record.

This is a precedent to Coinbase employees getting physical threats at their door just because e.g. some voter registration, utility company, bank, credit card, or court record decided to release their name and addresses on the internet. People could show up at some Coinbase software engineers' apartment doors with guns demanding they send BTC to arbitrary addresses.

asah · 4h ago
AFAICT it's impractical to keep residential addresses 100% private/secure - too many ways to get an address from any number of companies, organizations and governments that collect it for various reasons.

Plus numerous ways to infer your address from other data sources, including apps that grab GPS on friends' cellphones when they visit, etc.

Finally, shutting down paid data brokers seems virtually impossible in practice, which means anybody googling you can pay $20 and get everything.

Remember, the issue isn't lazy goodguys but even slightly motivated badguys, who then use third party scripts to do the data collection.

Just jail them. Make it a felony to release someone's PII without their written consent, and make data brokers illegal to begin with.

> numerous ways to infer your address from other data sources, including apps that grab GPS on friends' cellphones when they visit

These are not the main vector of transmission of personal information. Yes, Meta could probably do some graph analysis and infer this, but it's a lot of work, and their data leaks are rare in comparison to all the other companies, financial institutions, and governmental organizations, that freely post residential addresses on the internet and to data brokers for the world to Google.

> companies, organizations and governments that collect it for various reasons

KYC requiring addresses should be banned. Companies should not collect a residential address.

I mean... wasn't coinbase sort of scammy to begin with? Several years ago I gave them some USD, turned it into BTC, saw the value of the BTC go up, but when I tried to cash out was told that wasn't a thing that was supported by their platform. Later I was told I could apply for a $399/year credit card and could partially pay off the balance with BTC sale proceeds. I'm sure this was all disclosed somewhere in the terms of service I clicked through, and I only lost $1000 to their scheme.

But I've always wondered why people think this is how investment vehicles work. I monkeyed around with stock market bets and even Robin Hood allows you to cash out of your positions.

It's more likely you didn't "lose" $1k, but that you had "missed profits". And if you missed the profits because you didn't verify yourself earlier for withdrawal, then that's on you.

Coinbase supported direct bank withdrawals well before they launched their crypto debit cards.

ceejayoz · 4h ago
Your profits are your profits. Coinbase can hold them until you verify yourself for withdrawals, but they can't just take them.
kragen · 4h ago
It's really unfortunate that KYC regulations required Coinbase to have this information in the first place. We should be establishing strong social norms against sharing PII without a legitimate reason; this is not just an individual theft risk but a national security risk. Coinbase doesn't pay into your Social Security account, so they shouldn't have your Social Security number. They don't visit your house, so they shouldn't have your address. Etc.

Historically, although KYC regulations were widespread in Communist countries, they were unthinkable in most democratic countries until 9/11, which provided spy agencies with their golden chance to write their wishlist into law. But unfortunately that helps foreign spy agencies just as much as, maybe more than, it helps domestic ones.

They have no duty to report such things to relevant authorities even if it was discovered internally, so you could be looking at some corporate coverup that while not in on it, seeks to minimize liability/embarrassment.

Really, can you possibly tell if your Signal messages were compromised? Now that iPhones aren't really jailbreakable, you can't even see inside your own device.
